Title:
MICROCHIP, AND MICROCHIP ELECTROPHORESIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/041718
Kind Code:
A1
Abstract:
Provided is a microchip electrophoresis device capable of dispensing a specific
sample component from a sample and recovering the dispensed specific sample
component into a pod without being adsorbed by an electrode. A microchip to be
used in the microchip electrophoresis device is constituted to include a separate
passage (104), a dispensing passage (106) intersecting with the separate passage,
a recovery reservoir (pod) (118) communicating with the dispensing passage,
and a recovery electrode reservoir (120) communicating with the recovery reservoir
and having a recovery electrode. The microchip electrophoresis device separates
the specific sample component contained in the sample, through the separate
passage, dispenses the specific sample component through the dispensing passage,
and recovers the dispensed specific sample component into the recovery reservoir.
After this, the microchip electrophoresis device applies a voltage to the recovery
reservoir from the recovery electrode so that the sample component in the recovery
reservoir may leave the electrode.
